1.14.4 class paths not resolving - IDE Issue?

Today a weird problem has occurred.

I'm using Intellij Idea. I opened my mod project to find various imports were't resolving. Namely:

import net.minecraftforge.fml.loading.FMLPaths;

FMLPaths is red

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

LogManager and Logger are red.

Then within my script the logger is red, and events on the loading listeners are red. I tried refreshing dependencies, and reimporting the build.gradle to no avail. Even more strangely... if I attempt to run the mod, it works as though nothing were wrong.

I opened some of my other mod projects, same thing happens. It's affecting all of them. It appears to exist in the IDE only.

Additionally, I just opened one of my classes that appeared fine (wasn't highlighted in red in the IDE project tree) and its not showing errors on

import net.minecraftforge.eventbus.api.SubscribeEvent;

SubscribeEvent is in red.

Here is my build.gradle in case it helps:

buildscript {
    repositories {
        maven { url = 'https://files.minecraftforge.net/maven' }
        jcenter()
        mavenCentral()

    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true
    }
}
apply plugin: 'net.minecraftforge.gradle'
// Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.
apply plugin: 'eclipse'
apply plugin: 'maven-publish'
